RAILWAY WAGON OR TRUCK- SPECIFIGATION forming part of Letters Patent N0. 751,113, dated February 2, 1904;.

Application filed October 17, 1903, Serial No. 177,487. (No model.)

To aZZ whom it may concern.-

Be it known that I, J OHN SHAW, a subject of the King of Great Britain and Ireland, residing at Featherstone, near Pontefract, in the county of York, England, have invented a new and useful Improvement in Railway Wagons or Trucks Used for the Transport of Coal and other Minerals, of which the following is a specification.

This invention relates to railway wagons and trucks as used for the transport of coal and other minerals, more particularly to an improved device or apparatus to be used in conjunction with the bottom door or doors for the purpose of obtaining increased facility and expedition in the opening and closing of same.

In the drawings, Figure 1 is a side elevation, partly in section, of a hoppered truck or wagon having my invention applied. Fig. 2 is a plan of Fig. 1. Fig. 3 is a sectional end View of the truck or wagon, showing the doors open. Fig. 1 is a sectional end view of same, showing the doors closed. Fig. 5 is an enlarged detail of the bracket 6, hereinafter referred to. Figs. 6 and 7 are enlarged details of the spring 9, hereinafter referred to.

Similar letters refer to similar parts throughout the several views.

In the case of ordinary railway-trucks I propose to use one door 6 on each side of the center longitudinal Z, the said doors 6 being hinged to brackets 6, each bolted to the inside of the sole Zr: of the outer framework of the wagon and closing inwardly toward the center longitudinals Z. Attached to each door is a curved arm or lever a, the outer or projecting ends of these arms or levers (Z being when the doors are open in a suitable and convenient position at the side of the wagon for handling. By depressing the arms or levers a, each door Z2 is easily returned to its closed position with one hand, where it is retained against the specially-constructed end of the bottom door-band r and firmly secured by means of a cranked locking-bar h, suspended from brackets Z, bolted to the center longitudinals Z of the wagon, the said locking-bar being turned on its axis by means of a crank 0, attached to the said locking-bar h, and attached toand operated by a sliding bar 0, ex-

tending to the outer side of the wagon and terminating in a suitable handle 8 outside the framework of the wagon. When the door 6 is fastened, the handles, referred to, is secured in its position by means of a lipped pin (Z, which passes through the said sliding bar 0 and secures it to the bracket m, attached to the under side of the sole is of the wagonframe.

The mocZas operrmch is as follows: The ordinary lipped pin (Z (which passes through the sliding bar 0 and bracket m) is withdrawn and the handle 8 of the sliding bar 0 pulled outward, thus moving the said locking-bar 72., which holds the door Z) closed, in position under the door-band r. This releases the door 5, which falls outward to the side of the wagon against the springs f and g, allowing the coal or other mineral or material to fall out of the wagon. The same round of operation is repeated with the other door. After the wagon is emptied the doors Z) are returned to their closed position by depressing the curved arm or lever a, as already described, and are retained in that position by pushing back the sliding bar 0 with the handle 8, as previously described, and the handle 8 is then secured in its position by the pin CZ.

It will be understood that the wagons are preferably hoppered wagons made with sloping sides j and sloping ends; but my improvements can be applied to any wagon or truck requiring bottom doors.

In hoppered wagons the doors are so arranged as to form the bottom of the wagon within the hoppered part except the space occupied by the central longitudinal Z. 'On this center longitudinal Z is fixed a triangular piece of timber and sheeting 19, so that no coal can lodge thereon. If desired, the hoppered wagon may be constructed in an elongated form with two or more cross-timbers fitted with triangular timbers and sheetings, each with its own set of doors operated in the manner described.

It will be observed that by reason of the doors falling from the center of the wagon toward the sides and being checked and directed by means of a spring f, attached to the sole 7c of the wagon, and a spring 9, attached by a strap or to the under side of the door 5, the falling coal is prevented from spreading over the railway-line, the coal taking the direct course into the chute or receptacle into which it is to be delivered.

In order to prevent pieces of coal or other material lodging on the upper end of the door when open, and thus interfering with the closing thereof, the top end of the door 6 is rounded at g to a quarter-circle and fits closely within a corresponding recess formed in the bracket 6 and in the lower edge of the Wood hoppering and sheeting j, the said sheeted sides 1' of the wagon projecting suificiently over this curved or rounded portion q of the door to prevent the coal from lodging thereon.

In carrying my said invention into practice both operations of closing and securing the door are performed simultaneously, one hand being used for closing the door and the other for securing it, thereby greatly facilitating the handling of the wagons. Also with my arrangement the doors are closed by the person operating the same from the outside of the wagon only and not, as heretofore, by the operator having to go underneath the wagon, at great personal risk.

By this invention a large quantity of coal or other minerals can be dealt with in a very short time.

hat I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, with a railway-wagon, and discharging-doors hinged to the sides of its bottom portion; of handle-arms for operating the said doors, supports secured to the middle part of the bottom of the said wagon,

cranked locking-bars for the said doors journaled in the said supports, and handle-bars for oscillating the said locking-bars.

2. In railway wagons or trucks in which the coal or other material is discharged through bottom doors opening outward, the mechanism for controlling and operating said doors, comprising curved arms a, bracket 6, sliding bar 0, handle 8, pin (Z, bracket m, crank 0, locking-bar 7L, bracket 2', springs f and g, strap a, and door-band '1', all arranged and operated substantially as described.

3. In railway wagons or trucks in which the coal or other material is discharged through bottom doors opening outward, the mechanism for controlling and operating said doors, comprising curved arms a, sliding bar 0, handle s, crank 0, locking-bar h, and bracket 71, all arranged and operating substantially as described.

4:. In railway wagons or trucks in which the coal or other material is discharged through bottom doors opening outward, the combination of, hinged bottom doors each opened closed and secured independently of the other by mechanism arranged and operated as described, with springs attached to the wagon or truck body and springs attached to the under side of the said doors, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN SHAW.
